OUTPUT for Saftey Door while Printing

Mane660

Hello,
i need some tips how to configurate Repetier so that a Door closes while Printing

I use this RADDS Board

Am i able to configurate the Start G-Code, Pause G-Code and End G-Code so that if the print starts there is a Command in the
Start G-Code which says Servo PWM1 = 1
And when the End G-Code is started it should do Servo PWM 1 = 0

Is there an option to do something like that?
Or should i use another Pin on the Board?

Best regards

Repetier

You really open a door using a servo?
Use

- M340 P<servoId> S<pulseInUS> R<autoOffIn ms>: servoID = 0..3, Servos are controlled by a pulse with normally between 500 and 2500 with 1500ms in center position. 0 turns servo off. R allows automatic disabling after a while.to control if assuming servo is configured correctly. Firmware has no function to automaticaly open/close doors, but you could add it with our event system.

no, i want to use the Servo Pin as a Output for an Door Lock Mechanism because of Saftey Reasons.

so can i configurate the M340 Pin so that if the Start G-Code is executed the first Servo Pin gives a 1 Signal?

why don´t you use the already implemened safety door Switch?
it´s a Input stopping the Printer when door is not closed

how to use it? i cant find that :)

use Repetier-Firmware configuration tool for version 1.0.0dev / section Endstops

found it thank you :)

Added a door switch in Version 1.0.1, latest firmware. Get error when compiling at Line 67 in commands.cpp at this location (see below).

Compile Error:

sketch\Commands.cpp: In static member function 'static void Commands::checkForPeriodicalActions(bool)':

Commands.cpp:67: error: 'LaserDriver' has not been declared

LaserDriver::changeIntensity(0);

exit status 1

'LaserDriver' has not been declared

Code:
void Commands::checkForPeriodicalActions(bool allowNewMoves) {

Printer::handleInterruptEvent();

EVENT_PERIODICAL;

#if defined(DOOR_PIN) && DOOR_PIN > -1

if(Printer::updateDoorOpen()) {

if(Printer::mode == PRINTER_MODE_LASER) {

LaserDriver::changeIntensity(0);

}

#endif

Somehow getting past if(Printer::mode == PRINTER_MODE_LASER) even though I don't have SUPPORT_LASER in Configuration Tool checked.

Repetier

That was written with laser in mind, so if you hav eno laser it should look like this

#if defined(DOOR_PIN) && DOOR_PIN > -1 if(Printer::updateDoorOpen()) { #if defined(SUPPORT_LASER) && SUPPORT_LASER if(Printer::mode == PRINTER_MODE_LASER) { LaserDriver::changeIntensity(0); } #endif } #endif
so it does not call the laser off function.

Using your online configuration tool, I leave the box for SUPPORT_LASER unchecked and Default Printer Mode indicates Fused Filament Fabrication. Compiles fine and printer runs parts with no errors. When I go into Door Open configuration under Mechanics tab and include switch information, I get the aforementioned compiler error every time. I am using an Arduino Due with RADDS. I have tried this with other computers and always get the same results. Simply changing the Door Open to Not Installed eliminates the error. I agree with you that the program looks correct and the line LaserDriver::changeIntensity(); should not be executed but it is in this configuration. I have not gone through all of the code yet to figure it out.

Repetier

Did you try my modification that should solve the compile error? It adds the changeIntensity code only if a laser is compiled in.

forengineer

OK. I put in the changes and it eliminated the compilation error. Thanks!
